Abstract
A flow rate meter that includes a container of known and fixed volume. Electrodes, or sensors, are placed inside the container at several different heights. An electronic circuit uses the electrodes, or sensors, to measure the time it takes this container of known and fixed volume to fill a certain distance with water or water-based solution. The electronic circuit calculates the flow rate in engineering units from this elapsed time by knowing the volume of the container between the fixed electrodes.
